A beautiful first sight

Kalm is a beautiful first sight when you look at your device. It's soft, it's modern, it's clean – always tinted in your wallpapers colors so it fits right in.


Kalm shows the current weather on your lockscreen for either your current location or the first location of your Weather App. You'll never forget to bring your umbrella, your gloves or your bathing suit.
Want to see the condition as well? You can either display the current temperature only, or add the condition or location to it.
If you want to add some color to your weather Kalm let's you disable the tinting of the weather condition icon, so if it's sunny you will get your native yellow sun. Don't like the icon at all? You can just hide it!

Up next

Kalm also shows you what's coming up in your calendar or any reminders you've set. You won't miss any important events anymore and will always know what's up next. 
Have many calendars? Don't worry, with Kalm you can decide which calendars to use. Select any calendar you want and disable those pesky National Holiday and other subscribed calendars. You can also tell it to show full day events or not. Wondering which calendar the event comes from? Just enable the color indicator and a small colored bar will indicate from which calendar the event comes from!
If you like living on the edge, you can set the maximum days ahead to one day and Kalm will only show events that occur the next day. If you like to be prepared, set it to one week and you'll be ready for your next event.
If you're a busy person and have many upcoming events or reminders, you can now show up to 5 events/reminders on your lockscreen!


You can align Kalm, choose a different wallpaper color and change the adaptive colors saturation or brightness with ease, or even disable the adaptive colors completely – however you like it. Kalm also changes the alignment of the lock icon and colors the time and the Up Next label if you want it to. If you like it bolder you can now also adjust the font weights of each element.
Feeling overwhelmed with all the upcoming events but still want to show them? You can now switch to a more compact style of Kalm which will display events and reminders in only one line and doesn't clutter your lock screen as much.
Annoyed by Kalms automated colors? Just select your own by providing a # Hex code and override the colors. You can also change the offsets of the position of Kalm and the padding between the notifications.
Bored by the stock date format? Create your own date format by using the formattings provided by
